PIXEL DETECTOR, DETECTOR, TOMOGRAPHY IMAGE GENERATION SYSTEM BY EMISSION OF PóSITRON, METHOD PERFORMED IN CONJUNCTION WITH A SCINTILLATOR, METHODS TO PRODUCE A MEDICAL IMAGE, AND TO DISABLE DETECTOR DETECTOR, DETECTING CELLS, DETECTING A DETECTOR AND, CALIBRATION METHOD FOR AN IMAGE GENERATION DETECTOR A radiation detector (10) includes an array of detector pixels (22), each including an array of detector cells (50, 50 ', 50 "). Each detector cell includes a photodiode (52) polarized in a rupture region and digital circuits (54, 54 ', 54 ") coupled to the photodiode, and configured to emit a first digital value in a quiescent state and a second digital value sensitive to the detection of a photon by photodiode. Digital trigger circuits (60, 60 ', 60 ", 84) are configured to emit a trigger signal indicative of the start of an integration period, sensitive to a selected number of one or more detector cells in transition from the first digital value for the second digital value Digital reading circuits (66, 82) accumulate a count of a number of detector cell transitions from the array of detector cells from the first digital state to the second digital state over the integration time period.
